Abstract

An air compressor noise dampener. The dampener includes a housing having at least one inlet and at least one outlet. At least one baffle is secured within the housing in between the inlet and the outlet. The baffle includes an opening offset from the outlet so that sound waves traveling into the outlet hits a portion of the baffle prior to traveling through the opening. The present invention further includes a tube fluidly connecting the outlet with an intake of the air compressor.

Claims (41)

1. An air compressor noise dampener comprising:

a housing including at least one inlet having a perimeter defining area and at least one outlet having a perimeter defining an area;

at least one baffle secured within the housing in between the at least one inlet and the at least one outlet, wherein the at least one baffle includes an opening having a perimeter defining an area, the opening in the baffle positioned such that the area defined by the perimeter of the opening in the baffle does not overlap the area defined by the perimeter of the at least one outlet; and

a tube having a first end connectable to the outlet and a second end connectable to an intake of an air compressor.

2. The air compressor noise dampener of claim 1 , wherein the housing includes four sidewalls, a top wall, and a bottom wall, wherein the bottom wall includes the at least one inlet and is disposed above bottom edges of the four sidewalls, the top wall includes the at least one outlet, and the bottom edge of at least one of the four sidewalls is recessed to allow air to pass through.

3. The air compressor noise dampener of claim 2 , wherein the at least one inlet includes a pipe secured to the bottom wall.

4. The air compressor noise dampener of claim 1 , wherein the at least one baffle includes a plurality of baffles disposed above and below one another, wherein each of the plurality of baffles is a plate having a first end opposite a second end.

5. The air compressor noise dampener of claim 4 , wherein the plurality of baffles includes a first baffle having a first baffle opening formed through the first end, a second baffle having a second baffle opening formed through the second end and a third baffle having a third baffle opening formed through the first end, wherein the second baffle is disposed in between the first baffle and the third baffle.

6. The air compressor noise dampener of claim 1 , wherein the at least one outlet includes a first threaded port and a second threaded port.

7. The air compressor noise dampener of claim 6 , further including at least one tube fitting and a plug, wherein the at least one tube fitting includes a male threaded connector mechanically fastened to the first threaded port, wherein the plug includes a male threaded connector mechanically fastened to the second threaded port.

8. The air compressor noise dampener of claim 1 , further including an air filter covering a passageway through the at least one outlet.

9. The air compressor noise dampener of claim 1 , further including a mount bracket connected to an outer surface of the housing and operable to secure the housing to the air compressor.

10. The air compressor noise dampener of claim 1 , wherein the opening in the baffle is positioned such that the area defined by the perimeter of the opening in the baffle does not overlap the area defined by the perimeter of the at least one inlet.

11. An air compressor noise dampener including:

a housing having a first side, a second side, an inlet having a perimeter defining an area and an outlet having a perimeter defining an area;

a first baffle located in the housing having a first end located adjacent the first side of the housing, a second end located adjacent the second side of the housing, and an opening adjacent the first end, the opening having a perimeter defining an area;

a second baffle located in the housing having a first end located adjacent the first side of the housing, a second end located adjacent the second side of the housing, and an opening adjacent the second end, the opening having a perimeter defining an area;

a third baffle located in the housing having a first end located adjacent the first side of the housing, a second end located adjacent the second side of the housing, and an opening adjacent the first, end, the opening having a perimeter defining an area; and

wherein the first baffle is closer to the inlet than to the outlet and the area defined by the perimeter of the opening in the first baffle does not overlap the area defined by the perimeter of the inlet.

12. The air compressor noise dampener of claim 11 , wherein the third baffle is closer to the outlet than to the inlet and the area defined by the perimeter of the opening in the third baffle does not overlap the area defined b the perimeter of the outlet.

13. The air compressor noise dampener of claim 11 , wherein the second baffle is located between the first baffle and the third baffle and the area defined by the perimeter of the opening in the second baffle does not overlap the area defined by the perimeter of the opening in the first baffle or the area defined by the perimeter of the opening in the third baffle.

14. An air compressor noise dampener including:

a housing having a first side, a second side, an inlet having a perimeter defining an area and an outlet having a perimeter defining an area;

a first baffle located in the housing having a first end located adjacent the first side of the housing, a second end located adjacent the second side of the housing, and an opening adjacent the first end, the opening having a perimeter defining an area;

a second baffle located in the housing having a first end located adjacent the first side of the housing, a second end located adjacent the second side of the housing, and an opening adjacent the second end, the opening having a perimeter defining an area;

a third baffle located in the housing having a first end located adjacent the first side of the housing, a second end located adjacent the second side of the housing, and an opening adjacent the first end, the opening having a perimeter defining an area; and

wherein the third baffle is closer to the outlet than to the inlet and the area defined by the perimeter of the opening in the third baffle does not overlap the area defined by the perimeter of the outlet.

15. The air compressor noise dampener of claim 14 , wherein the first baffle is closer to the inlet than to the outlet and the area defined by the perimeter of the opening in the first baffle does not overlap the area defined by the perimeter of the inlet.

16. The air compressor noise dampener of claim 14 , wherein the second baffle is located between the first baffle and the third baffle and the area defined by the perimeter of the opening in the second baffle does not overlap the area defined by the perimeter of the opening in the first baffle or the area defined by the perimeter of the opening in the third baffle.

17. An air compressor noise dampener including:

a housing having a first side, a second side, an inlet having a perimeter defining an area and an outlet having a perimeter defining an area;

a first baffle located in the housing having a first end located adjacent the first side of the housing, a second end located adjacent the second side of the housing, and an opening adjacent the first end, the opening having a perimeter defining an area;
